Uji Adaptasi Beberapa Kultivar Tanaman Kentang (Solanum tuberosum L.) di Dataran Medium

Abstract

Potatoes as a subtropical plants require low temperatures for growth, especially during the formation of tubers that require optimum temperature of 180C. In the tropics, the temperature in a single location with a height of more than 1,000 meters above sea level. Planting potatoes in plain medium allows will demonstrate different levels of adaptivity in various cultivars of potato. The purpose of this study was to determine the growth of several cultivars of potato by using shade and without shade in plain medium. This research was conducted in the village of Batu Layang, District of Sibolangit, Deli Serdang district with altitude of 700 meters above sea level from September to November 2015. The treatments were 2 factors, N0: without shade, N1: using shade and cultivars of potato, namely V1: Medians, V2: Kastanum, V3: Amabile, V4: Maglia and V5: Atlantic using Petak Design Divided and repeated 3 replications. The results showed that giving shade was not significantly different, giving shade to the various cultivars also showed the effect is not real, and influence between cultivars of potato is very real for the varieties Amabile with other cultivars in height parameters, number of leaves, stem diameter, and not significant with whole other cultivars in the parameter tuber number and weight of tubers
